Although a man is in custody, Philadelphia police are not saying why after the city middle and high schools were placed on lockdown this morning.

About 8:55 a.m. Philadelphia police were in pursuit of a suspect in the general area of the middle and high school campuses, Police Chief Bill Cox said.
As a safety precaution the school initiated a lockdown as part of their crisis management plan.

A message sent out by the school said, "At no time was there any incident on the campuses of the High School or the Middle School. This measure was taken only out of an abundance of caution as we were alerted by our security personnel."
City School Superintendent Terry Larabee said, "As always, the safety of our students, staff, and faculty is our first priority."

The school administrative team will meet and debrief to insure that all measures were properly taken and to insure that swift and immediate steps are taken to correct any areas needed.

By 9:30 a.m., Cox said, the suspect had been taken into custody and the lockdown had been lifted.
